BOB-SLED.

SPECIFICATION forming part of Letters Patent No. 619,433, dated February14, 1899.

. Application filed May 6. 1898. Serial N0. 679,968. (No model.)

To all whom it nfl/ty concern,.-

Beit known that I, JOSEPH B. PAINE, a citizen of the United States,residing at Alcester, in the county of Union and State of South Dakota,have invented certain new and useful Improvements in Bob-Sleds; and I dodeclare the following to be a full, clear, and exact description of theinvention, such as will enable others skilled in the art to which itappertains to make and use the same.

The invention has relation to bob-sleds, and more particularly to meansfor connecting the runners to the cross-piece or bolster to permit of arocking motion of one part with respect to the other, thereby preventingundue jars to the body of the sled incident to the runners passing overany obstructions or inequalities in the road.

The object of the invention is to provide a sled of this character whichshall be simple of construction, durable in use, and comparativelyinexpensive ofy production.

With this object in view the invention consists in certain features ofconstruction and combination of parts, which shall be hereinafter morefully described and claimed.

In the drawings, Figure l is a perspective view of as much of a bob-sledas is necessary to illustrate the invention. Fig. 2 is a verticalsectional view through the bolster, knee, and runner.

In the drawings, 1 denotes the runner, 2 the knee, and 3 the bolster.These parts may b e 0f any well-known or approved construction. Thesides of the knee are preferably strengthened or reinforced by metallicstraps 6, bolted in place and provided at their upper ends with eyes 7.

8 denotes an elongated staple, the vertical limbs 9 of which projectthrough the bolster or cross-piece of the sled and receive nuts 10 attheir upper ends.

11 denotes jam-nuts secured to the lower ends of the vertical limbs 9and serve to prevent the bolster being forced down against thehorizontal portion 12 of the staple. The upper ends of the strengtheningor reinforcing straps are connected to the horizontal portion 12 of thestaple and are prevented from coming in contact with the under side ofthe bolster by reason of the nuts 11, which hold the portion 12 awayfrom the bolster, thus permitting of a free forward rocking movement ofthe bolster, which would not be the case were the portion 12 of thestaple permitted to come in contact with the under side of the bolster.

13 denotes a brace which is connected to the inner strap of each kneeand has its upper end formed with an eye pivoted to the portion 12 ofthe staple. A jam-nut 14 is screwed upon the inner end of the portion 12of the staple and serves to prevent the upper end of the brace movingoutwardly along the portion 12 of the staple, thereby preventing thespreading of the knees.

From the foregoing description, taken in connection with theaccompanying drawings, the construction, operation, and advantages ofthe invention will be readily understood without requiring an extendedexplanation.

I am aware of the fact that I am not the first to provide a rockingrunner for a bob-sled.

I am also aware of the fact that staples have been employed for thepurpose of connecting the knee with the cross-piece or bolster of thesled, and would have it distinctly understood that I do not seek toclaim such constructions broadly; but

What I do claim, and desire to secure by Letters Patent, is-

The combination with the bolster, knee and runner, of a bob-sled, strapssecured to the knees and having eyes at their upper ends, an elongatedstaple having its vertical limbs passed through the bolster and itshorizontal portion through the eyes of the straps, nuts secured on theupper ends of the vertical limbs, nuts on the lower ends of the verticallimbs to hold the horizontal portion of the staple below and free fromcontact with the under side of the bolster, a diagonal brace, the lowerend of which is connected to the inner strap ofthe knee, and the upperend of which is formed with an eye pivoted to the horizontal portion ofthe staple, and a stop or nut to prevent the longitudinal movement ofthe eye on the horizontal portion of the staple, and thereby preventspreading of the knee, substantially as set forth for the purposedescribed.

In testimony whereof I have hereunto set my hand in presence of twosubscribing witnesses.
